Answer 1

Answer:

x=9.16

Step-by-step explanation:

first cross multiply in the LHS

then you will get (4x^2-19x+20)/(x^2-7x+2)=25/3

then on cross multiply you will get

3[(4x^2-19x+20)]=25[(x^2-7x+2)]

now open brackets and multiply then bring similar terms to one side and cancel

then u will get

equation 13x^2-118x-10=0

now find x using formula

$x = (- b + - \sqrt{b {}^{2} - 4ac} ) \div 2a$

where here a= 13

b=-118

c=-10

then u will get the ans
